Application and my 23, mos. Serial 1w. mam.

Be it known that 1, lines A. IRvINe, a citizen of the United States, residmg at State 0 Connecticut, have invented new and useful Improvements in Tobacco-Pipes, of which the following is a specification.

The invention relates to tobacco pipes. Objects of the invention are to provide a protected from the elements when used outdoors; which may be conveniently placed in the pocket when lighted; which provides a cool and hygienic smoke; which may be manipulated simply and rapidly; which may be thoroughly and readily cleaned and which, while possessing these features, is of compact structure and attractive appear ance. These and other objects of invention will in part be obvious and will in part more fully appear herein.

The invention consists in the novel articles, parts, improvements and combination herein shown and described.

The accompanying drawings, referred to herein and forming a part hereof, illustrate one embodiment of the invention the same serving in connection with the description herein 'to explain the principles of the invention.

Of the drawings 2, Figure 1 is a perspective view of a pipe constructed in accordance with the principles of the invention with the bowl in the open position; Fig. 2 is a'se'c tional view with the bowl in the closed position and showing additional parts; Fig. 3 is a sectional view showin a different arrangement of parts and fig. 4 is a detail of one feature of the invention.

Referring to the accompanying drawings, illustrating an embodiment of the invention, a pipe is shown having a bowlpart 1 and a part 2 shaped to close the bowl and having an outlet aperture 3-, through which the smoke may pass from the ignited tobacco in the ipe bowl directly to the mouth of the smo er or indirectly thereto throutgllia further conveyer. The bowl 1 and t e part 2 which is adapted-to close the bowl are relatively movableflso that the bowl may be opened and closed as desired. A- suitable smoke passage from the bowl 1 to the outlet aperture 3 is provided. Connections be tween the bowl 1 and the part 2,which may I be opened in the inverted position.

be styled for brevity the shaped part, are provided to permit movement between said parts so that the bowl may be opened or closed and that there may be a smoke passage from the bowl'tothe outlet aperture 3 in both the opened and closed positions. I have chosen in the present embodiment to make said parts movable laterally, as shown in Fig. 1 and the particular form of connection shown herein is a pivotal connection 5 between said parts. The smoke passage is further shown in this embodiment as passing within said pivotal connection. An exteriorly threaded collar 6 is shown at the pivotal connection 5 threaded both into the bowl 1 and the part 2 and having its intri or bored in line with the smoke passage 7. The smoke passage is further shown as passing along the bowl and entering it at 4 at the opposite end thereof.

It will thus be understood that the pipe can be opened as shown in Fig. 1 of the drawings, charged with tobacco, lighted, the smoke passage connecting the bowl and the outlet being operative to permit the smoker to draw on the pipe and ignite the tobacco thoroughly. The ipemay then be closed and smoked until t e tobacco is entirely consumed.

Suitable means for supplying air are provided and in this embodiment ducts 8 are shown passing through the part 2 into communication with the interior of the bowl.

If desired, a guard plate 9 may be em ployed whichmay be movable to open or close the mouth of the bowl and will serve to retain the tobacco therein should the bowl Such plate, if usedy'may conveniently be pivoted concentrically with the bowl itself by means of an a erture-iO. The plate 9' is shown provide 1 with openings 11 to permit the air; t0 pass therethrou gh. If desired also a per foratemember 12' may be used between the smoke passage and the tobacco in the bowl to hold! back the tobaccofrom the aperture 4 while" ermitting the smoke to pass therethrou According to one feature of the invention means for supplying cool air to the smoke 'arecontemplated and in connection therewitlr acollecting chamber between the ear supply and the outlet aperture 3. In the present embodiment, therefore, acool an 1nlet 13 is shown between the bowl and the smoke outlet and it is further shown near the beginning of the smoke passage. There is also shown herein, located between the 5 said air inlet 13 and the outlet aperture 3 a collecting chamber 14, and it maybe conveniently located within the member 2. A screw threaded plug 15 is-shown for giving access to the smoke passage and the adjacent end of the bowl for cleaning purposes and a similar member 16 for giving access to the collecting chamber 14. The member 2 is shown further provided with a dished part 17 opposite the bowl 1, which serves as a receptacle for certain of the deleterious products resulting from the combustion of the tobacco.

The invention contemplates in one of its aspects providing a frictional closure for 20 the collecting chamber 14 and by one feature contemplates also providing an absorbent material 20 within said chamber. In the present embodiment a device combining these features is shown, comprising a memher 18, preferably cylindrical, fitting friction tight into the chamber 14. Said member may be made of resilient material and is shown provided with a slot 19 therein, one I purpose of which is to give a snug frictional fit in the'chamber 18.

' The safety and convenience of a pipe constructed in accordance with the principles of this invention will be apparent from what has already been stated, as the combustion takes place within a closed chamber which is at the same time readily opened either for charging, lighting or cleaning. Furthermore the combustion being at the bottom of the charge of tobacco, certain of the unde- 40 sirable products of combustion are immediately received into the part 17 without coming inv contact with the unburnt tobacco in the bowl of the pipe. Certain volatile elements which it is desired to eliminate,

and which pass over with the smoke are condensed by the cool air entering at 13 and are received into the collecting chamber 14, while at the same time the air serves to lower the temperature of the smoke and thus enhance its flavor.

Where the chamber 14 is providedwith a carrier having an absorbent material, the condensed elements referred to above are taken up by the absorbent material, and

thus quickly and effectively removed from the pipe when desired.

- It will be understood that the invention possesses other advantages some of which will be obvious herefrom and others learned to throu h use of the invention.

Whlle certain changes in form are shown herein it will be understood that same are illustrative rather than restrictive and that various changes in form may be madewithout departing from the principles of the invention as pointed out in the claims and without sacrificing the advantages of the invention. 1 i

What I do claim as my invention and desire to secure by Letters Patent, is: 7

1. A pipe including in combination abowl part, a part shaped to close the bowl and having an outlet aperture, and a pivotal connection between said parts to openor closethe bowl by a pivotal movement only and to have a smoke passage from the bowl to the outlet in both the open and closed positions.

2. Apipe including in combination abowl part, a part shaped to close the bowl and having an outlet aperture, and a pivotal con- 30 nection between said parts acting to open and close the bowl by a'pivotal movement only and a smoke passage within said pivotal connection. r I
